2 very thin value river raise possibilities

[corsakh]

Hand1: Its a very thin call, let alone raise. Meh, I suppose you have a chance to fold out a five, but nothing you beat calls you here.

Hand2: I make a crying call.

In both hands, raising would never even cross my mind.

Raising these isn't for value, it basically turns your hand into a bluff, unless you are playing against a HUGE donk. I would probably call both but expect to be losing a decent % of the time. I would also 3bet both of them pf, though calling w/ 99 is OK. And I would play the first 99 hand faster on the flop/turn.
